MCAT: Biochemistry Questions and Answers | Latest Update | 2024/2025 | 100% Verified What is the function of chaperone proteins in cellular biology? Chaperone proteins assist in the correct folding of newly synthesized proteins and prevent misfolding or aggregation. Describe the role of ATP in cellular energy transfer. ATP provides energy for cellular processes by releasing a phosphate group through hydrolysis, which drives biochemical reactions. How do allosteric enzymes di...

AAMC MCAT Exam 4 QUESTIONS AND ANSWERS RATED A+ 2023|2024 Most cytochrome P450 enzymes alter the activity of drugs by: A. phosphorylating them. B. dephosphorylating them. C. oxidizing them. D. reducing them. - ANSWER C. oxidizing them. cytochrome p450 acts as monooxygenase, where an oxygen atom is inseted into substrate, thereby resulting in oxidation of substrate. Given that antibiotics like erythromycin are metabolized by estrogen-sensitive P450 enzymes within the liver, which g...
